AUGUSTUS S. MILLER, OF MINNEAPOLIS, MINNESOTA, ASSIGNOR TO MARY MILLER, OF SAME PLACE.

MOP-WRING ER.

SPECIFICATION forming part of Letters Patent No. 553,654, dated January 28, 1896.

Application filed May 22', 1895 Serial No. 550,211. (No model.)

T0 aZZ whom it may concern.-

Be it known that I, AUGUSTUS S. MILLER, a resident of Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Mop-\Vringers; and I do hereby declare the following to be a full, clear,- and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in mop-wringers, the object of the invention being to produce a mop-wringer which shall be simple in construction, cheap to manufacture, easy to apply to a pail and which shall be effectual in all respects in the performance of its functions.

\Vith this object in view the invention consists in certain novel features of construction and combinations and arrangements of parts, as hereinafter set forth, and pointed out in the claims. I

In the accompanying drawings, Figure 1 is a plan view of my improved mop-wringer. Fig. 2 is an end view. Fig. 3 is a bottom plan view.

A represents a frame comprising two bars a a, each having an integral arm I) I), respectively, at one end, connected together by an integral web 0. The opposite ends of the bars a a are also provided with uprightarms 61 d, disposed parallel with the arms I) b and in alignment therewith. frame A is made with a depending arm 6 having a hole for the reception of a bolt e whereby to attach the device to a pail. The other end of the frame is provided with a laterallyprojecting arm 6 having an inclined lug or car e", which latter is perforated for the accommodation of a bolt 6 which acts in conjunction with the bolt 6 to secure the device to a pail. The arms 1) cl are made with elongated slots ff for the reception of the journals f of a roller B, and the arms I) d are made with elongated slots 9 g for the reception of the journals of a roller 0. The journals 9 of the roller 0 project beyond the arms 1) cl, and to one of said journals one end of a spring h is attached. The spring h is coiled between its ends, and the other end To the j ourthereof is secured to the arm a.

One end of the nal at the other end of the roller C one end of a spring h is attached, said spring it being also coiled between its ends, and its other end is secured to a log 71 projecting from the arm 6 From this construction and arrangement of parts it will be seen that when a mop is drawn between the rollers the roller C will yield against the resistance of the springs h h. It is intended that the roller B shall bear a normally fixed relation to the roller 0; but it has been found desirable that some means be provided for adjusting said roller B relatively to the roller 0. For this purpose yokes i z' are made to embrace the arms I) d, and these yokes are provided with perforations for the reception of the journals of the roller B, the yokes thus forming, in effect, journal-bearings. Each yoke 1' is made in its end with a hole for the accommodation of the plain portion of aset-screwj adapted to screw into the arms Z) and (Z. By turning the set or thumb screws j the relation of the roller B to the roller 0 may be readily adjusted so that in their normal positions said rollers will be nearer to 01' removed farther from each other to accommodate mops of different sizes.

The arms a a being connected together only at one end, the opposite end of the frame, between the rollers, will be open for the passage of a mop-holder when the mop is to be drawn between said rollers. It is desirable that after the mop-holder shall have been passed between the rollers the opening at the end of the frame A through which it shall have been passed be closed, so as to confine the mop between the rollers while the water is being wrung from it. For this purpose a latch-bar k is pivoted between its ends to one of the arms of the frame A and adapted to project across the opening at the end of the frame. The latch-bar is retained normally in position to close the end of the frame by means of a spring Z, one end of which is attached to said latch-bar and the other end to the frame, the latch-bar bearing normally against a stop m on the frame. The latchbar 70 is made near its free end with a notch 70, which engages a pin k on one arm of the frame. The latch-bar thus also serves as a brace between the two arms of the frame and the latter can, therefore, be made quite light without weakening it and without any liability of the spreading of the frame.

When the mop-head is passed through the open end of the frame, the latch-bar will yield to permit the insertion of the mop between the rollers, and when the mop shall have wholly entered the frame the latch-bar will be automatically closed by the action of the spring I.

My improvements are very simple in construction, cheap to manufacture and effectual in all respects in the performance of their functions.

Slight changes might be made in the details of construction of my invention without departing from the spirit thereof or limiting its scope, and hence I do not wish to limit myself to the precise details of construction herein set forth; but,

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a mop wringer, the combination wit-l1 a frame, of a roller mounted therein, springs connected with the axle of this roller for throwing the latter normally inward, a roller bearing a normally fixed relation to the yielding roller, and means for adjusting the fixed roller relatively to the yielding roller, substantially as set forth.

2. In a mop wringer, the combination with a frame having slotted arms, of a yielding roller mounted in two of said arms, a roller bearing a normally fixed relation to the yielding roller and having its journals passing through two other slotted arms of the frame, yokes adapted to receive the journals of the fiXed roller and embrace the arms through which said journals pass, and thumb screws passing through said yokes and engaging said arms, whereby to adjust the fixed roller relatively to the yielding roller, substantially as set forth.

3. In a mop wringer, the combination with a frame having slotted arms, of rollers having journals passing through said slotted arms, springs secured at one end to the journals of one roller and at the other end to the frame, yokes constituting bearings for the journals of the other roller, and thumb screws passing through the ends of said yokes and engaging the arms of the frame through which the journals of said last-mentioned roller pass, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

AUGUSTUS S. MILLER.
